NOISELESS STEAM WATER-HEATER.

Specification of Letters Patent.

l-atenteo. may 29, 1906.

To all whom, it may concern."

Beit known that I, JoH GEoRGE IIUF-' NAGEL, a citizen of the UnitedStates, residing at Scranton, in the county of ,Lackawanna and State ofPennsylvania, have,invented certain new and useful Improvements inNoiseless Steam Water-Heaters; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to improvements in mufflers, and particularly tosteam waterheaters.

The object of the invention is the provision of means for facilitatingthe mufiling or discharging of steam from an outlet WlllCll may.

be positioned within a tank or receptacle containin a'liquid. 4 I

Wit this and other objects in view the invention consists of certalnother novel constructions, combinations, and arrangements of parts, aswill be hereinafter fully described,

illustrated in the accompanying 'drawin s,

and more particularly pointed out in t e claims hereto appended.

In the drawings, Figure 1 is a view in side I elevation of a deviceconstructed in accordance with the present invention. Fig. 2 is avertical longitudinal sectional view of the device depicted in Fig. 1,and Fig.3 is a transverse sectional view of the same.

Referring'to the drawings by numerals, 1

designates a cylindrical primarycasing which is provided with transverseapertures 2. At each end of the casing there is formed an annular inteal extension 3.

An auifiary cylinder 4 is positioned upon the parallel cylinder 1between the annular extensions Eor ends 3- 3. This cylinder 4 is formedof a wire mesh or screen. Between the primary and auxiliary cylinders 1and 4,

respectively, a compartment 5 is formed;-

Within this compartment there is positioned porous or fibrous fillingmeans as, for mstance, hem which insures of the noiseless discharge 0the steam from the apertures 2' of the primary cylinder 1.

The auxiliary wire-mesh or screen cylinder 4; is positloned between andlies flush with the outer surface of the annular extensions or ends 3 3of the primary cylinder.

Integral with one of the ends 3 is a thread ed tubular portion 6. Theconducting means for the steamas, for instance, a hose or pipeisconnected to the muffler by means of this tubular ortion 6. It is to benoted that the bore 0 the tubular portion 6 is of the same diameter asthe bore of the primary apertured cylinder 1. By reason of this thesteam is not retarded in its passage into the muffler. The passage ofthe steam from the interior of the primary cylinder to the outeratmosphere is retarded bytwo meansto wit, a cylindrical hemp jacket anda wire-,mesh cylinderQ Although I referably use hemp for forming thecylindrlcal fillin' jacket, in some instances other fibrous fil ingmeans may be employed.

My improved muffler is particularly adapted to be secured to thedischarge end of ahose or tubing which is positioned within a tank orreceptacle containing liquid which is to be heated. The discharge of thesteam through the three cylinders or casings constituting my muffler iscomparatively noiseless.

What I claim is Y 1; A device of the character described, comprising aprimary cylinder, formed with rows of sta gered radiating aperturestherein, enlarge ends formed ntegral with said cylinder, an auxiliarywire-mesh cylinder secured to said primary cylinder and lying flush withthe outer surface thereof, and a cylinder of fibrous material interposedbetween said primary and auxiliary cylinders.

2 A device of the character described, comprising a cylinder, formedwith staggered apertures therein, closed at one end, a tubular threadedportion upon its opposite end, a

Wire-mesh cylinder positioned between the ends of said primary cylinder,and a hemp filling positioned between said primary and auxiharycylinder.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN GEORGE HUFNAGEL.
